⚙️ Operating Instructions & Sequence

1. Match Voltages: Double-check that your battery pack’s nominal and maximum voltage matches the selected WAPUNO charger output rating (e.g., 48V battery = 54.6V charger).

2. First Step (DC Connection): Plug the charger’s DC output cable securely into your electric vehicle or battery pack charging port.

3. Second Step (AC Connection): Connect the AC power lead to the wall outlet. The digital screen will light up to display live status during active charging.

4. Completion: Once full charge capacity is reached, the smart auto-cutoff engages. Disconnect the AC wall plug first, then remove the DC output cable from your vehicle.
